Just wondering what these guys are like for platform stability and overall service quality. I'm particularly interested in trading interest rate spreads (across the entire curve from 3mo to 10yr) on LIFFE and Eurex. I understand that they have recently or are in the process of changing clearers so if there are any issues or background info that would be useful, too. Don't fancy paying an arm and a leg for J-Trader (!) with my present broker so I thought I'd ask.
